Is My Cpu Throttling My Gpu?

In today’s technology-driven world, the CPU and GPU are two crucial components of any computer. Both these components need to work in harmony to ensure the seamless performance of your system. However, sometimes problems arise, which affects the overall performance of your computer. One of the most common issues is CPU throttling, which may be responsible for slowed-down graphics processing.

CPU throttling is a process where the CPU reduces its performance to decrease the system’s temperature. Although it is intended to prevent the hardware from overheating, it can have adverse effects on the system’s overall performance. Many people wonder whether CPU throttling can affect their computer’s graphics processing unit or GPU. In this article, we will discuss the role of CPU in graphics processing and provide you with tips to fix the issue of CPU throttling affecting your GPU.

Is My CPU Throttling My GPU?

Possible explanation:

CPU throttling is a condition where the central processing unit (CPU) of a computer reduces its clock speed or performance to prevent overheating or extend battery life. This may also affect the performance of other system components, such as the graphics processing unit (GPU), if they depend heavily on the CPU for data processing or synchronization. Therefore, it is possible that your CPU is throttling your GPU if you observe symptoms such as:

– Lower than expected frame rates or graphical quality in games or other graphics-intensive applications.
– High CPU usage or temperature while the GPU is not fully utilized.
– Occasional stuttering, freezing, or crashing of the system.
– Errors or warnings related to CPU or GPU performance in hardware monitoring or diagnostic tools.

To confirm whether your CPU is actually limiting your GPU, you can try the following steps:

– Monitor the CPU and GPU usage and temperature using software such as MSI Afterburner, CPU-Z, or HWMonitor.
– Run benchmarks or stress tests that stress both the CPU and GPU, such as FurMark or 3DMark, and compare the results to those of similar systems with similar specs.
– Adjust the power settings or fan settings of your CPU and GPU to see if it affects the performance. You may also try disabling any background processes or applications that may consume CPU resources unnecessarily.
– Check the BIOS or UEFI settings of your motherboard to see if there are any options that relate to CPU or GPU throttling, such as thermal protection or power management.

If you find out that your CPU is indeed throttling your GPU, there are some possible solutions, depending on the cause and severity of the issue:

– Improve the cooling of your CPU and GPU by adding more fans, changing the thermal paste, or upgrading the heatsinks. This may reduce the temperature of both components and allow them to operate at their full potential.
– Adjust the clock speeds or voltages of your CPU and GPU using overclocking or undervolting tools. However, this requires some technical knowledge and may void your warranty or damage your hardware if done improperly.
– Upgrade your CPU and/or GPU to a more powerful model that can handle the current workload without throttling. However, this can be expensive and may also require other upgrades, such as a better power supply or more RAM.
– Contact the manufacturer or a qualified technician for further assistance and diagnostics, as there may be other issues or software conflicts that contribute to the throttling.


1. Question: How can I check if my CPU is throttling my GPU?

Answer: You can use monitoring software like MSI Afterburner or GPU-Z to check GPU temperature and clock speed while running a heavy CPU task. If the temperature or clock speed drops significantly, it means that your CPU is throttling your GPU.

2. Question: What are the common signs of CPU throttling affecting GPU performance?

Answer: The common signs of CPU throttling affecting GPU performance are reduced frame rates, sudden FPS drops, stuttering, and increased input lag.

3. Question: Can overheating of the CPU cause throttling and affect GPU performance?

Answer: Yes, overheating of the CPU can cause throttling and affect GPU performance as the system tries to reduce the temperature by slowing down the CPU, which can lead to drops in frame rates and stuttering in games.

4. Question: How can I prevent CPU throttling from affecting my GPU performance?

Answer: To prevent CPU throttling from affecting GPU performance, you can try cleaning the components, improving airflow, reducing CPU usage, and upgrading your CPU or GPU.

5. Question: Does having an inadequate power supply affect CPU and GPU performance?

Answer: Yes, having an inadequate power supply can affect CPU and GPU performance as the components might not receive enough power, leading to throttling and reduced performance. It is recommended to have a power supply that can supply enough power for your components.


In summary, it is important to be aware of CPU throttling and its potential effects on your GPU performance. If you notice that your games are running slower or your graphics are not as crisp as they should be, it may be worth investigating whether your CPU is throttling your GPU. By taking steps to manage your CPU usage and monitor your hardware performance, you can ensure that your computer is running at peak efficiency and enjoying optimal gaming experiences.
